    Habit
    Perennial; caespitose. Rhizomes short; pachymorph. Culms erect, or arching; 200-500 cm long; 10-20 mm diam.; woody; without nodal roots. Culm-internodes terete. Lateral branches dendroid; extravaginal. Branch complement many; in a horizontal line; thinner than stem. Culm-sheaths deciduous; 9.8-13.3 cm long; without auricles. Culm-sheath blade lanceolate; erect; 0.5-1.2 cm long; glabrous on surface. Ligule an eciliate membrane; 0.2-0.5 mm long. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades deciduous at the ligule; lanceolate; 11.7-18.3 cm long; 5-9 mm wide. Leaf-blade venation without cross veins. Leaf-blade surface glabrous, or pilose; hairy abaxially. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence a panicle. Panicle open; lanceolate; dense; nodding; 6-10 cm long. Primary panicle branches appressed. Panicle branches glabrous. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets linear; dorsally compressed; 6.7-8.6 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets linear; dorsally compressed; 6.7-8.6 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.3-0.5 mm long; 1 length of upper glume; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume ovate; 0.3-0.5 mm long; 0.05 length of adjacent fertile lemma; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex obtuse.
    Florets
    Basal sterile florets similar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 3.1-3.4 mm long; 0.4-0.5 length of fertile lemma; chartaceous. Lemma of upper sterile floret ovate; 3.4-4 mm long; chartaceous. Fertile lemma ovate; 7.2-7.6 mm long; coriaceous; without keel. Lemma margins involute; covering most of palea. Lemma apex apiculate. Palea tightly convolute around flower; 1 length of lemma. Palea keels contiguous above a sulcus.
    Flowers
    Lodicules 3; membranous. Anthers 3. Stigmas 2.
    Fruits
    Caryopsis with adherent pericarp; apex unappendaged.
